It was 2am when Dean was woken up by Castiel groaning and rolling out of bed to be sick. Dean opened his eyes in time to see him run out of the bedroom and into the bathroom, he cringed when he heard him gag and the rush of liquid hit the bowl.

"Dean" he whined pitifully leaning against the radiator and pouting feeling ill and sore. Dean rolled his eyes pulling on a t-shirt and padded into the bathroom folding his arms.

"I told you this would happen"

Castiel frowned holding out his arms till Dean sighed and came over dropping down to hold him close. Dean wrinkled his nose flushing the contents away and holding still while Castiel climbed into his lap wrapping his legs around his waist and nestling into his neck.

"Are we sleeping in the bathroom now?"

"Hold me" he murmured shivering and inhaling the smell of his skin.

"You stink of beer, sick, and the seaside" Dean murmured shaking his head and leaning back against the wall.

"The sea? Why would I…" he said and trailed off pulling back with a gasp. "Oh my god"

"What?" Dean murmured seeing his pupils widen and his face pale even more.

"Promise me you won't get seriously angry with me or…Balthazar" he said clinging to him.

Dean narrowed his eyes pushing him back slightly. "What did you do, Cas"

"Well…Balthazar's in love with me"

"I know that"

"But he wanted to know if his feelings were true, he was telling me everything about how he loves his taken best friend and how he'll never be able to find someone else…" Castiel said lightly. Dean rolled his eyes but continued to listen to him.

"So he asked for a test, well a kiss, and I said yes" he murmured avoiding his eye contact. Dean froze and tilted his head blinking wildly as he digested that information and leaned forward gripping his chin and pulling it back towards him.

"You kissed him!"

"No! Well yes, but it was only like this" he murmured pressing a chaste kiss to his lips and pulling back. "It was a little test and I was drunk, Dean, but he got horny and tried again"

Dean pressed his lips into a tight white light looking away from him.

"I'm sorry, I'm so sorry, I didn't mean it" Castiel pleaded leaning back towards him cupping his cheeks. "It was a silly little test but it doesn't mean I like him, I like and love him as my best friend, Dean, you know that"

Dean clucked his tongue into his cheek and finally nodded. "Okay, I understand it was a test, a stupid one I might add, and it's not cheating I guess but don't you ever do it again! I'll find Balthazar and cut his balls off if he even dares kisses you again for some fucked up confirmation of feelings, you're mine"

"I promise" Castiel murmured clinging to him hard. "I'm yours"

"Are you going to be sick again?"

Castiel nodded pulling away and heaving into the toilet. Dean sighed rubbing his back gently when he coughed and gagged.

"I feel like death"

"Well don't get drunk"

"It's fun"

"Oh to be young and foolish" Dean murmured getting a poke from Castiel and chuckling. "It's late, I'm tired, and I want to sleep"

"You can't leave me!"

"Watch me big boy" Dean said standing up and walking towards the door. He peered back to see Castiel sat on the floor eyes downcast and shivering. Dean closed his eyes feeling overwhelming guilt and sighed collecting the blanket and pillows for them and coming back in.

"Come here" he murmured to him watching him get up and stumble confused. Dean eyed his pale and sickly face as he dried the bath and dropped the blanket and pillows in.

"If we are sleeping in here, we're sleeping in this. It means climbing in and out but they always say sleeping in the bathroom makes you feel better" Dean murmured helping him in and wrapping the blanket around them. They had an awfully large bathtub that Dean was more than grateful for right now. Castiel shivered burrowing into Dean's warmth as they settled down for sleep.

"Am I forgiven?" Castiel murmured against Dean's neck.

"Drinking? Yes. Kissing your best friend for a test of his feelings? No." Dean muttered into his hair. "You have serious making up to do"

"Sex?"

"Lots of it" Dean murmured breathing warm air down his neck and smiling softly when Castiel hummed in approval. Dean knew when Castiel had drifted back off to sleep by his deep breathing and snuffles in his sleep. It was relaxing for now but the stiffness of the bath was uncomfortable and he peered down at Castiel with hard eyes.

"The things I do for you, you own me big time!" he hissed cuddling him close for warmth. Castiel hummed fisting his hand into his shirt feeling waves of sickness and dizziness penetrate him but knowing the toilet was only metres away soothed him and kept it at bay.

The phone rang loudly in the next room that morning much to the displeasure of both of them.

"Dean, answer it"

"You answer it"

"I'm sick!"

"Like that is an excuse and you're closer to getting out" Dean mumbled into his hair with his eyes closed.

"Dean, it's annoying"

"Leave it be"

"What if is important?"

"They'll ring again"

"I think it's Balthazar"

Dean scoffed in disgust wrapping his arm around his middle and keeping him in place.

"He's dead to us now, rest in hell" he murmured and laughed when Castiel moaned as it restarted ringing.

"Dean!"

"Fine!" Dean said struggling out of the bath and getting out answering it.

"Hello? Hello?" he said down the phone and groaned throwing down the phone. "Silent phone calls, again!"

"Track the number?"

"No caller I.D" Dean called back and turned towards the kitchen. "Oh I need coffee"

Castiel struggled out of the bath and closed his eyes swaying feeling like death. His mouth tasted like sand and sick and his body screamed in protest.

"Coffee" he croaked wandering into the kitchen. Castiel leaned his forehead against his back with a fake sob. "I'll do anything if you make me coffee and cuddle me all day"

"What about uni?"

"I quit" he murmured walking to living area and dropping down on the couch face first.

Dean chuckled pouring a second cup. "Sure you do"

"Dean, I feel like you've beaten me several times with that huge pan we have" he murmured turning his face towards him. "I hate Balthazar"

"Good to hear"

"I don't really"

Dean hummed amused dropping the cup down gently on their coffee table.

"Do you want the blanket?"

"Yes please"

Dean walked away hearing him groan and sit up to drink it. Dean threw it on his head when he was finished and was satisfied to hear him whine.

"Dean, my head is sore!"

"You're such a child, man up" Dean said switching on the television.

"Go away" Castiel murmured wrapping his body in a cocoon. "If you're going to be mean, you can go away"

Dean chuckled reaching over and tugging him over so he could wrap his arms around him.

"You're adorable drunk and hung over, Cas, what am I going to do with you?"

"Be nice and hold me?" he murmured wrapping the blanket around him. "I'm also very sorry"

"Cas, it's fine"

"It's not! I shouldn't have done it" he whispered.

"I blame Balthazar, not you" Dean said with knowing eyes.

"I let him"

"He shouldn't have asked! He knows how he feels and he was gagging for you" Dean said with hard eyes looking away.

Castiel smiled gently nuzzling his cheek. "I like it when you get jealous and possessive"

"You're mine, baby" he murmured capturing his lips and pulling away. "Forever"

"That's a long time"

"We have a long time" Dean said with a half-smile which faltered when the phone rang. "This person is dead!"

Castiel sighed looking over to Dean who answered it and waited. "I can hear you fucking breathing! I don't know how or why you are doing this but I swear to god…one more phone call and I'm calling the police. They'll track you down, you motherfucker" he hissed and slammed the phone down. "I will"

"I'm sure" Castiel said when he sat back down with a huff. "Every ten minutes last night, who has our phone number?"

"A lot of people, it's probably kids, Dean"

"Well I'll kill them"

"I thought you loved kids?"

"I do! But not the little brats" Dean said with a shudder. "If we have a baby, it'll be a star child"

Castiel swallowed reaching up and trailing his hand into the short brown hair. "Babies"

"What about them?"

"A lot of work, responsibility, they change your life and sometimes not for the better" he muttered.

"Yeah, it's a little baby, Cas, they're hard work"

"Do you think…do you think we could handle it?"

Dean gave him a sidelong glance for a long minute before nodding.

"I think we could, I think we'd struggle like any normal parent who has a child for the first time but I think we'd be okay" Dean said with a smile turning back to the TV. "But baby talk is a long way away, Cas, so we don't have to talk about it now"

Castiel didn't reply. Dean simply watched cartoons feeling like a little kid again when he noticed the time.

"I have to go to work"

"No"

"Yes" he muttered kissing him briefly and getting up. "I want you to stay here, drink water, and sleep"

"Please stay"

"Cas, I make the living here and it's your own fault for getting drunk on a Thursday" he muttered kneeling down and kissing his forehead. Castiel moaned at the banging in his head and watched him get up and dress in his overalls.

Castiel frowned watching him walk around the apartment collecting keys and money.

"I'll be back at five"

"Fine"

"I love you"

"I may love you too"

Dean smiled opening the door and looking back to him, Castiel looked back giving him his best wounded puppy look.

"Stop it"

"Stop what?"

"Giving me the puppy eyes, you have Gem to keep you company" he said and winked as he closed the door. Castiel sighed and looked towards the bedroom.

"Gem!" he called and watching their lazy kitten run out to greet him. "Hey"

Gem purred when he placed her on his knee and stroked her.

"We have a long day" he murmured when she licked his fingers and rolled onto her back for a tummy rub.

Lily instantly knew Dean was in the garage and bit her lip contemplating how to ask when she stumbled and tripped landing painfully on her side. Dean heard the noise and walked out to see her on the floor wincing.

"Shit, are you okay?" he said moving towards her and stopping. "Hey, you're…Lily, right?"

"Yes" she murmured looking up at him with a sweet smile.

"Cas' friend" he said dropping down to inspect her. "What happened?"

"I tripped I think and my ankle…" she said gesturing at it. "It's sore"

Dean frowned deeply and sighed with a nod. "Come on"

Lily watched as he stepped forward picking her up gently, she gasped wrapping her arms around his neck frozen in surprise till he placed her down on the desk chair.

"Let's have a look see" he muttered peering at the red ankle. "It looks a little swollen"

Dean moved away to get some ice from the fridge. Lily tilted her head inspecting him and straightened when he came over.

"Hold this to your foot" he ordered and stepped back looking over her. "So why are you here?"

"Looking for Castiel, he isn't in" she said staring up at him. "Do you know where he is?"

"Yep, he's in bed sleeping off a bad hangover" he muttered shaking his head. "He's a naughty boy"

Lily didn't smile back when he smiled and she simply looked over to the car.

"Is that a Chevy Impala 67?" she said with a small smile.

Dean gaped and turned towards it with a nod. "You know your cars"

"My adopted father loves them" she said. "I have a fine interest in them"

"I see that, yeah she's my baby" he murmured patting the top. "My dad gave her to me just before he died"

"I'm sorry to hear that" she murmured softly. "It's a beautiful car"

Dean smirked with a nod looking over to her. "I don't know why Castiel never introduces me to his friends…I think it's because I usually hate them"

"You like me?" she said tilting her head.

Dean laughed and shrugged. "You're doing well so far"

Lily blushed looking down at her feet. "That's very good to know, I like Castiel a lot, and he's a good friend"

Dean smiled at her and nodded. Lily eyed him and looked down twisting a silver ring around her finger.

"You remind me of someone I used to know"

"Oh" he said opening the bonnet.

"He's like you in personality and the way you treat Castiel" she said with envy and want shining in her eyes that faded the moment Dean looked over.

"He must be an awesome dude" he said with a grin.

"Yes, yes he was" she whispered biting her lip and sniffing deeply. "Thank you for this, Dean, it won't be forgotten"

"You fell, darling, I wasn't about to leave you on the sidewalk" he said straightening up. "How does it feel?"

"Sore but manageable" she said removing the ice packet and straightening out her thin silk top showing off the top of her breasts. Lily noticed the way Dean looked down at them and away with raised eyebrows.

"I was wondering if I could ask a favour"

"Shoot"

"Cars, you know a lot about them?"

"Yes" Dean said gesturing around with a raised eyebrow.

"Would you teach me about them? I'd like to know, my adopted father never had time for my interests and I love cars as much as I love nursing" she said moving forward slightly. "I'd pay"

"Don't be daft" Dean scoffed and stopped looking over her. "You want me of all people to teach you everything to learn about cars"

"Yes" she said with a confident smile.

"Okay, you have a deal. When do you want to start?"

"Every Saturday?"

"That's my day with Cas"

Lily narrowed her eyes slightly and then nodded. "Sunday?"

"Are you sure?"

"Yes"

"Okay, Sunday mornings it is" he said pointing a finger at her. "10am start and we finish at lunch"

"Perfect" she murmured moving out and stumbling. Dean darted forward catching her arm and helping her out.

"My car is just down there, I should be okay from here" she said casting her eyes over to him. Dean let go and smiled softly.

"I'll tell Cas about our arrangement in case he freaks out that I'm pressuring you into it" he said and waved a hand at her. "This Sunday and don't be late"

"Never" she called back and walked slowly down the path. Lily looked back to the entrance and climbed in her car. Lily straightened pushing back her curls and peering down at her phone. Lily felt bad but she couldn't help it, he reminded her of Mark. The guilt rose up when she saw Castiel and Dean's home number on her phone. She had dialled it over 50 times hearing Dean shout and rage. It was hard to admit but it turned her on.

But the guilt wouldn't fade and she knew she would be hurting Castiel by doing this. Lily did like him as her friend and he was so good to her these past few weeks, but Castiel had what she had been looking for, for so long.

Lily opened her phone to look at her pictures. One of Dean leaving the apartment, in the garage, walking to the café, coming out of the café, on the phone, talking to a friend, another photo with Castiel that made her stomach churn but she kept it. It seemed okay in her mind, they were just photos. Was it a crime to take photos of people now, she wondered desperately. Lily started up the car heading towards her empty penthouse and ignored the screaming pain in her foot. Lily felt like she deserved it.

Castiel opened his eyes feeling disorientated and woozy when Dean opened the door.

"Hey, baby" he murmured coming over and smoothing his fingers into his hair. Castiel moaned reaching for him when he reared back.

"Five minutes, I smell of oil and I'm all dirty" he said and frowned when Gem circled his legs in greeting. "Move, cat"

Dean went into the bathroom stripping off and splashing cold water in his face. Dean was excited at the prospect of teaching and not history this time, his other love for cars was about to be tested.

"I saw Lily today"

"Oh?"

"She was looking for you and tripped over"

"Is she okay?"

"Yeah" Dean murmured pulling on a clean white t-shirt and sliding into the warm covers and holding him close. Castiel smiled inhaling his warm clean smell and wrapped his arms around his middle. "She hurt her ankle and I put ice on it…why didn't you tell me she was interested in cars?"

"Because I didn't know" he said with a frown. "Why?"

"She asked me for lessons on cars, I said yes, and it starts on Sunday"

Castiel moved his head back with a frown. "Seriously?"

"Deadly, she seems really interested and knew what a Chevy Impala 67 was" he said shaking his head. "You don't mind do you?"

"No, of course not" Castiel said tucking his face into the crook of his neck. "It's good you can share your wisdom"

"Is that sarcasm, Mr Milton?"

"No, Mr Winchester" he murmured and laughed when Dean tickled him.

"Feeling any better?" he whispered peppering kisses down his face.

"Much, I ate crackers"

"Oh really?" he whispered with a chuckle. "I'm proud of you, my little burger"

"What?" Castiel said confused when Dean laughed loudly startling Gem who ran out of the room.

"You said I was your burger last night"

"I did!"

Dean hummed nodding his head. Castiel could see the amusement shining in Dean's eyes and scoffed.

"I never"

"You did, Cas"

Castiel frowned at him and looked away towards the television.

"Anyway, you have a lot of making up to" Dean whispered huskily in his ear. Castiel smirked looking back towards him and nodded abruptly.

"Should I start now?" he whispered over his lips pushing him down on his back and straddling his waist. Dean smirked for a moment before meeting his kiss and opening his mouth wider when he pushed his tongue inside licking his mouth. Dean moaned arching up towards him when Castiel ground his hips into him.

"Shit, Cas" he hissed when he pulled away shimmying down to his belt and undoing it slowly to pull them down. Castiel took them off roughly staring at Dean in his black briefs, he didn't hesitate as he mouthed over his cock through the fabric. Dean gasped rolling his hips when the hot sensation tickled at his cock which hardened instantly.

"You've been a very naughty boy, Cas" Dean whispered gripping the top of his hair. Castiel moaned looking up at him with smouldering blue eyes.

"I better make it up to you" he murmured with a wink that made Dean's stomach flutter. Castiel slid his hands down taking off the black briefs watching the cock rise to attention, Dean groaned in relief when his mouth swirled over the head. Castiel took his time as he slid his hands down his inner thighs sucking and swallowing the head tasting the bitter taste of salt and Dean in his come.

"Cas, please" Dean begged fisting his hand into the covers and one in the softness of Castiel's hair. Castiel engulfed him in one moment eliciting a shuddering cry from Dean who arched his hips and spine. Sensations of pleasure ran across him like fire and he moaned restfully watching and feeling the slide of Castiel's lips on his sensitive cock.

Castiel listened to the moans of appreciation and want practically screaming from Dean. He sucked harder stroking and licking his tongue while massaging his balls in his other hand. Dean gasped seeing a white light and a hissing noise in his ears when he climaxed shooting his load down Castiel's throat. Castiel swallowed greedily till he was spent and boneless. Castiel smiled crawling back up to him and kissing him softly.

"You're amazing" Dean whispered spreading his legs so he could fit perfectly.

"There's plenty more coming"

"How do I deserve you?"

"Endless bad luck" he whispered and laughed when Dean brought him into a fierce kiss.

But the problem with happiness is you never know what's around the corner to ruin it and there is always something.

A/N: Your feedback has been awesome! I love writing Lily. She was going to be a boy but I changed my mind at the beginning. You'll begin to understand her, she's my character and you'll see how messed up she really is in upcoming chapters.

Enjoy!
